I think I may be needing a new motor ,,, I use my car for business and can't afford much downtime ... I'll know for sure this weekend but it sounds like a rod knock... oh well ,, got 30,000 out of a motor that was far enough gone I originally thought it'd never run again... If it is a spun bearing that lead to a failure would cleaning up the journal with 1500 grit and installing new rod bolts and a new bearing be a long term fix in your opinion or would it be best to swap out the motor? I run full synthetic oil and unfortunately had to drive the car about 80-100 miles after the apparent failure but the motor is still turning freely so I think the journal is worth inspecting..

My car/motor is a 97 2.4TC.. I need to know what is involved in an engine swap with a newer year motor,, more than likely if I find a low mileage yard motor it'll be 2000+ .. I understand there are some sensor differences... do I merely have to swap in the older type sensors and/or cut in new terminals on the harness or will this require a new 'puter that understands the sensors... also how to get around the egr/non-egr differences?
